V @ther objects and uses will be brought out n in thefollowing' description.

ln the dran-ingslligure l 'is afperspeetive 'view of a hand truckequipped. with in'i i5 proved safety appliance, "a portion of `one sideof the truck being broken away to show more clearly the trailer. Figs. 2and 3 are enlarged transverse sectional views taken re spectively onlines 2 2 and' 3*-3, Fig. l.

Fig. 4; is a transverse sectional view of the cross bur and bracketshowing the trailer leg in side elevation. in its extreme rearwardposition.

As illustratedthis hand truck comprises zr pair of oppositely disposedhandle bars- -1- spaced some distance' apart and di verging rearwardlyand held in fixed relationby suitable cross bars -2- and and an axle-4-, the letter bengseoured 9G to tlie'underside of the frontend of thetruck by bolts for receiving suitable wheels N65-,

A lifting flangeor bnr -'-7 issefiured to the front ends ofthe' upper'edges of the handle here l et en angle thereto and. transverselythereof and has its opposite ends pieferzibly.` provided with.rearwardly extending straps -S- which are securely ere provided withsuitable. handles-1L- ,ofthe axle and Wheels sonthatftthe truck freineconstitutes a lever a relatively 110 long arm provided with: handles anda relatively short am for receiving the load, thus adapting the'ti'uckfor liftingl and balancing and conveying heavyfreig t.4 The cross bar-Q- is preferably mortised intothe,

bolts -SF and -9-, thereby additionally holding these portions of thehandle bars 'in fixed relation.

As previously stat-ed, the axle 4eis secured by the -bolts -5- to theunderside of the front ends of the handle bars and -its opposite endsare preferably cylindrical and extend beyond said handle bars forreceiving the wheels -6- which are held in place by nuts l0- orequivalent fastening means onthe ends ofthe axle.

The safety appliance2 forming the subject matter of my presentinvention, preferably comprises atrailer leg 1l pivoted to a suitablebracket or hanger 12- which in turn is adjustably mounted upon a crossbar 13- and held in its adj usted position by a set screw -14=-, thecross bar -13- being adjustable lengthwise of the truck frame and issecured in its adjusted position at its ends to the underside thereof byclamping bolts 15- .as shown more clearly in Figs. l, 3 and 4. Thesebolts -15-, as shown in Fig. 3, are provided with hookshaped heads 1G-slidably engaged with the upper faces or edges of the handle bars -1-f,the lower ends of the bolts being extended downwardly at the inner sidesof said handle bars and passed through lengthwise slots 17- in theopposite ends of the cross bar 13 so as to allow said cross bar to beshifted longitudinally of the truck frame, the ends of the cross bar13rbeing held in their adjusted position against the underside of thehandle bars by nuts -18 on the lower ends of the bolts -'15-. This crossbarv4 is preferably of uniform size from end 4to end to allow thebracket I2- to be, adjusted longitudinally thereof" orv transversely ofthe truck frame for the purpose of shifting the trailer leg -11- to anydesired position between the handle bars to suit the convenience oftheoperator in placing either foot against the axle and forcing rthelifting bar -7- under the load in the usual manner. f

The bracket -12- is provided in its upper side with a recess forreceiving the bar -13, one edge of the bracket being pro-v vided with anoverhanging lip -19- form-- ing a guide groove for the adjacent 'edge ofl lthe I bar angles.

bracket is provided with an apertured lug for receiving the set screw-14, the latter lserving to engage the ladjacent edge of the bar*lforclam ing the bracket in its adjusted position an at the same time,permitting it to be -adjusted when necessary. This .bracket 12`"-is=also provided with pendant lugs -QQspaced apart for receiving betweenthem` the.A upper -end of the whileopposite -edge of the' bracketbetween the legs being substantially flat to engage and cooperate withasimilarly'll'attenedsurface -22- on the adja; cent end or heel of thetrailer leg -11--5 said-coacting flat faces constituting a stop' forlimiting the rearward movement of the trailer leg toa position atsubstantially right angles tothe plane of the 'tri'ick and at the sametime permitting the trailer leg to swing forwardly toward and from thevaxle 4'- foi' supporting This limiting stop or abutment 22- is disposedat the rear side of a .line drawn at right angles' to the truck framethrough the axis of the pivot -21- andis located in close lproximity tobut just above said pivot so as to allow the free end of the trailer legto 'swing through an arc of relatively long radius;l

The weight of'tlietrailer le is sufficient .to carry it'downw'ardly andorwardly as the rear end 4ofthe 'truck frame-is raised so that when itis free frbmengagementwith the floor or ground it will assume asubstantially vertical position ready to support [the truck'at' antilted angle. 'It also clear that when t ejtruck israised tol an uprightposition for receiving a load, the trailer arm willbe carried'forward byown gravity closer .to the axle or to' `the plane of the truck where it'is out of the way of the foot of the operator in engaging the axle toforce the lifting bar ,.7-'4 under such load, but, as soon as the rearend ofthe truck isro'cked downwardly with the load thereon-, thetrailer'leg -11,- automatically .rock rearwardly ready to engage thefloor or ground and thereby 4limit the downward movement of the truck incase the operator should wish to temporarily rest and will alsoeffectively prevent the descent of the truck upon the feet or 'legs ofthe ,operator in .case the handle should accidentally slip from thehands. Y

the truck at di'erent The .object in providing' for the adjustment ofthe trailer leg and support lengthwise of the truckis'to support thehandle bars vat the desired height according-'to the height' of the.operator. nThe object in providing 'the transverse adjustment of lthetrailer leg is to enable it to be brought yto one side or the'ot-her ofthe longitudinal center of the truck to suit theoonvenience of the,

operator in placing one foot or the other under the truck and againstthe axle' for forcing ythe lifting bar under the load. n

The operation of my invent-ion will now be readily understood uponreference to the foregoing description andthe accompanying drawing andit will be evident that the detail of construction and arrangement ofthe various parts may be modified without departing from the spirit ofthis invention and, therefore, I do not limit myseli;` to the preciseconstruction as yshown and described.

1. A hand truck having a pair of handl bars,'a cross bar adjustablelengthwise of the handle'bars, means for clamping the cross bar. inl itsadjust-ed position, a bracket on the cross bar, and a leg hinged to thebracket to swing lengthwise of the truck.

2. Ahand truck having a pair of handle bars, a cross bar attached to thehandle bars, a bracket adjustable lengthwise of and upon the cross bar,means for clamping the bracket FERRAND F. ELLis, R. S. HURLBUT.
